This species is distinguished by the presence of an acute bony projection at the tip of the snout, and the posterior nostril opening as a ventrally directed slit on the side of the head just above the upper labial flange, not visible externally; head pores are reduced in size and number, with only three pores in the infraorbital canal, four in the supraorbital canal, and none in the preopercular or supratemporal canals (Ref. 129618).
